Please run lspci -n so I can see the number associated with your subsystem id. I can't tell from the string being displayed. As you indicated above, the adapter could be any of 3 from the list.

I am not sure why you are getting the unsupported feature message. I want to see which version of the Gigabit ET Dual Port Server Adapter you have. I know this feature is supported on 8086:a01c and 8086:a03c. I know that 8086:a04c is a custom version for Dell. I am not sure if the Dell version works differently or not, but if that is what you have, I will try to find out about any differences.

Sorry, that I did not ask for the proper command. I meant to add the -n to lspci to see the subdevice information. You still need to keep the -v option to show that information. So the output I want to see is lspci -n -v. As far as I know, you should be able to use the bootutil to enable your flash. However, I want to find out the exact device you have so I can investigate if you need to do something differently.

The "-n" option will show the PCI ID numbers instead of substituting the strings. Here is an example from my lab machine:

A possible way around this might be to use the DOS version of the utility. If you make a DOS boot CD, you could use that utility to enable your flash. The Linux and Windows utilities both make use of a separate, installed iqv driver. The DOS version of the utility does not have that dependency, so using the DOS version of the utility might be away around the issue you are seeing.

If you use the DOS utility and see an unknown flash version, perform an image upgrade (-UP). I had to do that on my adapter when I used the DOS utility.

Just discovered we have to use the bootutil provided by dell, available from support.dell.com, filename Intel_LAN_13.5.0_DOSUtilities_A00.exe. Extract Intel_LAN_13.5.0_DOSUtilities_A00.exe and get the bootutil.exe inside. Boot into DOS and execute bootutil as usual.

After using the bootutil provided by Dell, I successfully modified the LAN card configuration.
